Supplemental Information
STUDY NOTES: Alkenone data for 4 tropical ocean sediment cores, determined at Brown University. Data set includes composite depth, age estimated from matching stable isotope data to the Lisiecki and Raymo (2004) benthic stack, Uk'37 measured, and the conversion to estimated sea surface temperature (SST). Stable isotope data were generated at Brown University by Steven Clemens and Warren Prell. Note that the stable isotope data for ODP722 come from Clemens et al. (1996), sampled at ~7 kyr resolution, so the ages associated with the samples have more uncertainties than the other data sets published in Herbert et al. (2010).
ABSTRACT SUPPLIED BY ORIGINATOR: Determining the timing and amplitude of tropical sea surface temperature (SST) change is an important part of solving the puzzle of the Plio-Pleistocene ice ages. Alkenone-based tropical SST records from the major ocean basins show coherent glacial- interglacial temperature changes of 1° to 3°C that align with (but slightly lead) global changes in ice volume and deep ocean temperature over the past 3.5 million years. Tropical temperatures became tightly coupled with benthic d18O and orbital forcing after 2.7 million years. We interpret the similarity of tropical SST changes, in dynamically dissimilar regions, to reflect "top-down" forcing through the atmosphere. The inception of a strong carbon dioxide-greenhouse gas feedback and amplification of orbital forcing at ~2.7 million years ago connected the fate of Northern Hemisphere ice sheets with global ocean temperatures since that time.
